SlPHON-PUMP.

SPECIFICATION forming part of Letters Patent No. 238,136, dated February22, 1881.

Application filed March 15, 1880. (No model.)

To all whom it may concern:

Be it known that I, WOLGOTT B.MANWAR- ING, of New London, in the countyof New London and State of Connecticut, have invented a new and usefulImprovement in Siphon-Pumps and I do hereby declare that the followingis afull, clear, and exact description of the same.

My invention relates to pumps of that class in "which the flow of theliquid is started by the pumping action of a collapsible bulb, and,after such initial flow, continuous by the siphon action of the tubewhich forms the pump.

The invention relates to details, and has for its object thesimplification of the apparatus, increase of the fluid by lesseningnecessary obstructions, and to prevent the liquid from rising into thecollapsible bulb. These details are fully illustrated in the drawingsand hereinafter described, and are particularly indicated in the claims.

Figure 1 of the drawings shows a side elevation of the pump, and Fig. 2a longitudinal central section.

In these figures, a represents the pipe or tube, which is inserted intothe barrel or other vessel from which the liquid is to be drawn. It isjoined to the horizontal tubular chamber A at preferably right anglesthereto. Between the point of junction of this pipe and the verticaltube 1; is a clack-valve, c, inclined, as shown, sufficiently to allowit to be closed by gravity. It is seated against a narrow flange fixedin an inclined position in the tubular chamber A, and is hinged by hookand link to the upper part of said flange, so as to rise and fallfreely. On the other end of the chamber A is another similar valve,similarly inclined, and on the same level. Between these two valves isfixed a vertical tube, 1), on the upper end of which is placed a nipple,d, for the collapsible bulb. This nipple is connected to a tube, 6,which extends inward and upward, opening toward the top or crown of theairtube 1). The effect of this arrangement of the pipe is, that when theliquid has been drawn by the rarefaction of the air up into the tube 12,and the air is again expelled from the bulb,

it is directed and impinges against the inner surface of the crown ofthe table, and from thence deflected equally and uniformly downwardagainst the fluid in the tube without disturbance. As ordinarilyarranged, the expelled air from the bulb is directed downward, andstrikes the surface of the liquid in the tube forcibly and unequally,thereby causing agitation of the liquid, and often throwing some of itinto the bulb but in the described improvements the force of the airdriven by the compression of the bulb is greatly lessened, and thecurrent is then equally distributed without disturbing the exposedsurface of the liquid.

It will be observed that what may be called the valve-chamber ispractically a continuation or part (slightly enlarged) of the wholesiphon-tube. The valves are on the same plane or level, and when theflow is once established it continues with only the trifling obstructionarising from the slight weight of the inclined valves. Further, as theair-chamber to which the collapsible bulb is attached is an independentand separate tube, with only a narrow opening into the siphon-tube, theair-space is economized, and the air is prevented from occupying otherportions of the pump, and is confined to the air-tube itself, wherebythe liquid is more certainly prevented from reaching the bulb.

It will be observed in the drawings that the horizontal tubular chamberA is formed with an inclined end, and provided with a threadedextension, to which the longer or discharge leg of the siphon isattached.

The discharge-leg may also be made in two parts, joined at the bend, asshown at 00. The parts are thereby made separable, both for conveniencein packing, or for cleansing, as well as to avoid liability of breakagein handling.

The valve next to the suction-pipe is located sufficiently in rear ofthe air-pipe, so that this pipe will not be covered by the valve when itis floated by the flow of the liquid.

Having thus described my invention, whatI claim as my invention is- 1.The air-pipe e, connected to the nipple of the collapsible bulb, andextending upward In testimony whereof I have signed my name 10 towardthe top or crown of the air-tube, as set to this specification in thepresence of two subforth. scribing witnesses.

2. In a siphon-pump, the combination of a 5 horizontal valve-chamber, avertical pipe, b, WOLOOTT BARBER MANWARTNG' connected to the horizontalchamber between Witnesses: the valves, and a collapsible bulb connectedB.
